Hi, the NPE was caused b/c the label attribute of inputText was null. The bug is here: https://issues.apache.org/jira/browse/TRINIDAD-969
Now.... it renders out somethings like (when no label is present): - Value Required when a label is present, it renders: label - Value Required the current situation is better as the NPE, but a bit odd. Solutions: -render the id of the component (this is confusing to users...) -render a style (like border:2px solid #C70000) + panelPopup that says ="Value Required" (for the particular component) the later needs some time, but I think that would be a good solution... (not tried anything here) -M On Tue, Feb 26, 2008 at 9:57 AM, Matthias Wessendorf <[EMAIL PROTECTED]> wrote: > Hi, > > thanks for filing the ticket on this. > stay tuned. > > -Matthias > > > > On Mon, Feb 25, 2008 at 11:26 PM, Steve Horne <[EMAIL PROTECTED]> wrote: > > In researching a bug in my application, I have created this example that > > recreates the problem, which seems to be a Trinidad bug... > > > > In order to reproduce, you should enter SPACES ONLY into the text field and > > submit the form.
